RAIL RAMP LEVELERS

NORMAL OPERATION

1.  To lower the rail ramp, depress and hold the LOWER 

button until lip is supported by the rail car.

NOTE:  At about 12” to 15” above dock height the rail 

ramp will enter the float range.

STORING LEVELER

1.  To store the rail ramp, depress and hold the RAISE 

button until the rail ramp is slightly past the full 

vertical position. Once ramp reaches slightly past the 

full vertical position, release the RAISE button.

LIP OPERATION

1.  To fold the lip the rail ramp must be in the lower mode. 

With the LOWER button depressed simultaneously 

depress the LIP button. With both buttons depressed, 

the lip will fold.

2. 

To  extend  the  lip  the  rail  ramp  must  be  in  the 

raise mode. With the RAISE button depressed 

simultaneously depress the LIP button. With both 

buttons depressed the lip will extend.

NOTE: The lip will only operate while the rail ramp is 

being operated outside the float range.

BELOW DOCK ENDLOADING

1. 

Extend  the  endload  arms.  The  endload  arms  must 

contact  the  rail  car  floor  to  provide  support  for  the 

ramp. Depress and hold the LOWER button. Before the 

leveler reaches the float range, simultaneously depress 

the LIP button to fold the lip completely. Once the lip 

is completely folded (pendant) the LIP button can be 

released. Continue depressing the LOWER button until 

the  leveler  reaches  the  float  range. The  rail  ramp  will 

lower until the endload arms are supported by the rail 

car floor. Endloads can now be removed from or placed 

on the rail car. 

2.  Once endloads have been removed the rail ramp can 

be placed into the rail car by depressing the RAISE 

button.  Once  the  rail  ramp  is  outside  the  float  range, 

the lip can be extended by simultaneously depressing 

the LIP button and the RAISE button. With the lip fully 

extended, both buttons can be released. The rail ramp 

can now be lowered or stored.
